The multiple components are matched, so that the storage and freshness retaining time of fruits and vegetables is effectively prolonged, loss of water in a storage process is reduced, mildewing, browning and sprouting are reduced, good glossiness, delicious taste and nutritional components of fruit and vegetable products are kept, the loss is reduced, and the economical benefit of the product is enhanced.

Description

A kind of coating antistaling agent
Technical field
The present invention relates to antistaling agent field, specifically, relate to a kind of coating antistaling agent.
Background technology
It is a global problem that fresh fruit of vegetables rots after adopting, and according to statistics, approximately there is 10 one 20% fresh fruit of vegetables in developed country because postharvest disease causes rotting, and developing country reaches 40 one 50%.Due to the backwardness of preservation technique, the fruit of the annual output of China directly waste and loss late up to 38%.For solving the rotten problem of postharvest fruit and vegetable, Shelf-life, people are to using antistaling agent in fruit-vegetable food.
The conventional antistaling agent of food has: benzoic acid is that countries in the world allow a kind of food preservative using, and it easily excretes with dung liquid in animal body, does not accumulate, and toxicity is low and cheap, occupies at present most domestic antistaling agent market; Butylated hydroxy anisole (BHA), is one of antioxidant of current international extensive use, and has very strong anti-microbial effect, is mainly used in edible oil and fat, and research on maximum utilized quantity is 0.2g/kg, and shortcoming is that cost is higher; Dibutyl hydroxy toluene (BHT), is one of antioxidant of current China output maximum, cheap, is 1/5 ~ 1/8 of BHA, but non-oxidizability not as BHA strong, the scope of application is identical with BHA, shortcoming is that toxicity is higher.
The focus of research concentrates on edible film-coating fresh-keeping method both at home and abroad at present.Edible film-coating is to take edible natural material as raw material, the film with porous network structure forming by different molecular interphase interaction, and be covered in food surface by forms such as parcel, dipping, coating, sprinklings.It can suppress the exchange of fruits and vegetables gas, reduces respiration rate, reduces moisture evaporation, stop the oxidation of exposing to the sun when air, preventing the raised growth breeding of microorganism, thereby be conducive to keep nutritional labeling and the color of fruits and vegetables, is a kind of effective fruit and vegetable preserving method.
But also there are problems in most of coating antistaling agent, the one, contain the chemical composition that human body is existed to harm, do not meet green safety requirement; The 2nd, plastics water proofing property is poor, and release period is shorter, and preservation is inhomogeneous, be difficult in order to be effective, the 3rd, plastics has larger infringement to organoleptic quality.
Summary of the invention
Of the present inventionly be to provide a kind of environmental protection, have no side effect, coating antistaling agent with low cost.
For achieving the above object, the present invention adopts following technical scheme:
A coating antistaling agent, films in the aqueous solution for every liter, comprises the component of following parts by weight:
Pomegranate rind extract 5-8g, konjacmannan 5-10g, cinnamomum japonicum volatile oil 10-15g, Extracts from Peanut Hulls 3-5g, all the other are solvent.
Further, the optimum ratio of antistaling agent is: film in the aqueous solution for every liter, comprise the component of following parts by weight:
Pomegranate rind extract 5g, konjacmannan 8g, cinnamomum japonicum volatile oil 10g, Extracts from Peanut Hulls 3g, all the other are solvent.
Further, described solvent is the acidic ethanol aqueous solution, and the volume ratio of ethanol and water is: 7:5, pH value is 3-4.
Further, the preparation method of described cinnamomum japonicum volatile oil is: the leaf of taking from the cinnamomum japonicum so drying in the shade is placed in pulverizer, clay into power, add distilled water (weight ratio is 1:4) and bead number, after soaking 5-6 h, by the way of distillation, distill extraction, extraction time is generally no more than 4 h, distill the complete heating that stops, after instrument is cooling, with the volatile oil in petroleum ether dissolution pipe, and be moved in collecting pipe with liquid-transfering gun, collecting pipe is placed in to refrigerator and allows benzinum volatilization obtain cinnamomum japonicum volatile oil.
Further, the preparation method of described Extracts from Peanut Hulls is: peanut shell is pulverized, and with the alcohol lixiviate 24h of 85-90%, filter residue lixiviate 1 time again, merges rotary evaporator recovery of alcohol distillation, and concentrate is dried, and obtains Extracts from Peanut Hulls.
Further, the preparation method of described pomegranate rind extract is: take dry granatum as raw material, after cleaning, pulverize, be placed in than 60% the ethanol for 1:4 and extract 1-3 time, extraction time is 7-8 hour, extraction temperature is 85-95 ℃, and extract is concentrated, dry, pulverizing, obtain pomegranate rind extract.
Further, the preparation method of this antistaling agent, comprises the following steps:
Step 1, by konjacmannan deionized water dissolving, the konjacmannan aqueous solution of preparation 1.0g/ml-2.0 g/ml;
Step 2, dissolves pomegranate rind extract with ethanol, be mixed with the pomegranate rind extract solution of 5.0 g/ml-8.0 g/ml;
Step 3, dissolves cinnamomum japonicum volatile oil with ethanol, be mixed with the cinnamomum japonicum volatile oil solution of 10 g/ml-15 g/ml;
Step 4, dissolves Extracts from Peanut Hulls with ethanol, be mixed with the Extracts from Peanut Hulls solution of 0.3 g/ml-0.5 g/ml;
Step 5, gets the 300ml konjacmannan aqueous solution, 100ml pomegranate rind extract solution, 100ml cinnamomum japonicum volatile oil solution and 100ml Extracts from Peanut Hulls solution and mixes, and with the acidic ethanol aqueous solution, is added into 1000ml, is mixed into coating antistaling agent.
Cinnamomum japonicum is used as medicine with bark and leaf, and can adopt the whole year, peels bark and dries in the shade, and blade can be adopted at any time, and using fresh herb or dry in the shade all can.In timber, containing compositions such as essential oil, eugenol, linalool, p-cymenes, have and have multiple medical value and developmental research to be worth.The volatile oil of cinnamomum japonicum, having certain preservation, can be used as antisepsis antistaling agent, and aspect protein decomposition antibacterial, that prevent meat, its effect is all good than potassium sorbate and Tea Polyphenols.
Extracts from Peanut Hulls, is a kind of flavone compound, and its main component is cyanidenon.Cyanidenon has anti-oxidation characteristics, can suppress the growth of staphylococcus and hay bacillus when 1:1350 (MX) concentration simultaneously, and catarrh bacterium, Candida albicans, proteus are also had to inhibitory action.
The water-soluble formation gelatinous solution of konjacmannan, degree of killing is high, stability and good film-forming property, is suitable as the matrix of coating-film fresh-keeping, and poly-the warding off of kanjak mannan also has the ability that suppresses pericarp browning and growth of microorganism.
Pomegranate rind extract, its chemical composition is mainly granatin (granatin), bacteriostatic test confirms, the alcohol extract of pomegranate and pericarp water decoction, have broad-spectrum antibacterial action, it has obvious inhibitory action to staphylococcus aureus, hemolytic streptococcus, comma bacillus, shigella dysenteriae etc.
Beneficial effect: component of the present invention is all that cost is low, easy to operate to human-body safety, nontoxic, non-irritating composition, can carry out use of large-scale production; Thereby various ingredients of the present invention cooperatively interacts and has realized the preservation and freshness time of effective prolongation fruits and vegetables, the forfeiture of minimizing moisture in storage, reduce go mouldy, brown stain and germination, keep good color, mouthfeel and the nutritional labeling of fruit and vegetable food, reduce the loss, improve product economy benefit.
